tower toppler

This release fixes memory leaks,
adds a proper program ending instead of an uncaught exception,
fixes all warnings when compiling (except for fread and fwrite),
makes the software compilable on modern systems,
adds included missions to the datafile instead of separate files,
and fixes joystick support.

A new mission: David1. New translations: Czech, Romanian, and Basque. The background music is included with the distribution.

Background music was written. Portugese and
Swedish translasions were added. A small bug that
made the toppler get stuck under very special
conditions was removed.

This release really includes a pasis mission this time, adds a Finish
translation, and updates the French translation.

This release removed the possibility for the toppler to get stuck when the elevator fell down and made it possible to not use internationalization under BeOS. The saving of bonus level option was fixed. Untested joystick support was added. The build system was updated and the sound files were moved into the data file. A two tower mission was added. Sticks in front of doors is now possible, meaning that elevators can now pass doors.
